What is incorrect about this orbital diagram?
Both arrows in the filled 2p box should be pointing the same direction
There is nothing incorrect with this diagram
In the there should only be 1 arrow in the first 2p box and one in the 2nd 2p box
All the arrows should be pointing the same direction.
No two electrons in the same atom can have the same four quantum numbers.

Pauli's Exclusion Principle
Hund’s Rule
Noble gas notation
All orbitals of equal energy (degenerate orbitals) are occupied by one electron before any single orbital is occupied by a second electron.

What is an orbit ?
An orbit is a part of the proton around the nucleus of an atom.
An orbit is a part of an electron around the nucleus of an atom.
An orbit is a part of the neutron around the nucleus of an atom

1s2 2s2 2p6
1s2 2s2 2p6 3s2
1s2 2s2 2p6 3s1
1s2 2s2 2p6 3s2 3p4
In 1s2, the 1 means
there is 1 electron
the electrons are in the 1st energy level
the shape is circular
there is a -1 charge
